This invention relates generally to apparatus for dispensing lubricatingoils, and more particularly to means adapted for operative applicationto an oil-containing 6 drum, whereby to prevent the seepage of waterinto the interior thereof.

It is customary for the oil dealers to deliver oil to retailers in largedrums having an inlet aperture into which the barrel of the pump may bescrewed, but it is a known fact that the top of the drum is relativelythin, and not adapted to take enough screwthreads to permit the barrelto be so screwed into the head as to impart the rigidity necessary tothe operation of the pump. In addition thereto the drum head is sothin,.and relatively flexible, that the pump cannot be securely fixed inposition, and operation of the pump handle constantly tends to disruptthe screw-thread connection between the drum headand the pump barrel, sothat. the latter soon wears out the threads in the head and becomesloosened therefrom, resulting in a wabbling motion of the pump wheneverit is used. Such motion obviously tends to accelerate disruption of thescrew threads in the aperture, and, since the drums are usually oroftentimes exposed to the elements, water and dirt will pass between thepump barrel and the wall defining said aperture, and the oil in the drumwill soon become contaminated.

The head of an oil drum is usually positioned at least one inch belowthe upper periphery of the drum sides, forming a basin adapted to catchwater and dirt, and the primary object of the invention is the provisionof means for positively preventing the seepage of water and dirt pastthe barrel of the pump "and into the drum. In the accomplishment of thisobject, I provide means for stiffening the drum head to minimize lateralmovement of the pump, and also means for preventing access of refuse tothe aperture which receives the pump barrel.

Other objects of the invention will be made apparent in the followingspecifications, so when read in connection with the drawings forming apart thereof.

1931. Serial No. 546,384.

Fig. 6 is a perspective view of the operat ing cam and differentiatinglocking lever, and,

Fig. 7 is a section on line 77 of Fig. 3.

Now referring specifically to the drawings in which like referencenumerals indicate like parts throughout the several views, and referringfirst to Fig. 4:, the numeral 1 indicates a metallic drum or barrel,having a top or head 2, positioned in a plane located slightly below thetop periphery 3 of the sides of the drum. The drum head 2 is provided onone side with an aperture 4, adapted for the reception of the barrel ofthe pump, and with a smaller aperture 5 on the other side, for thereception of a gage-stick 6, best shown in Fig. 2. The walls definingsuch apertures are provided with screw threads adapted to retaincastellated nipples 7 and 8, respectively.

A dish-shaped cover 9, best illustrated in Fig. 4, is formed of a sizeand shape adapting it for a close fit over and around the upperperiphery 3 of the sides of the drum. The underside of said cover isreinforced by metallic angle-rails 10, 11, extending transversely andcentrally across the inner face of the cover, said rails being rigidlysecured in position by screws, rivets, or by a spot welding process.

Resting upon and secured to the horizontal rails 10, 11, near the frontends, is a plate 12, and an eccentric 13 is mounted on said plate, andis rotatable by means of a vertical shaft 14 having a top adapted for asuitable wrench or a removable handle. As indicated in Fig. 6, theeccentric is rotatably positioned in an aperture formed in the end of alink 13, the other end of the link being pivotally con nected at 15 tothe front rail 16 of a rectangularly-shaped frame having side rails 17and 1.8, adapted for longitudinal reciprocation in either direction,under suitable rotation of the cam 13, the rails 17 and 18 being guidedby strap members 29, 29 one for each rail- The front end of each of therails 17 and 18 is pivotally connected to the front rail 16, whereby topermit a differential movement of the rails, and the extreme end portionof each of the rails 17 and 18 is beveled to wedge-shaped form, for apurpose to be later referred to.

As best indicated in Fig. 2, the cover 9 is apertured concentricallywith the aperture 4 in the drum head 2, to permit the reception of thepump barrel. The pump is best illus trated in Figs. 1, 2 and 4 and maybe of standard design except as modified as herein disclosed. The lowerportion of the pump is constructed to form a bell 20, having atransversely extending, interior partition 21, through which the pumpbarrel 22 extends. On the inner face of the wall of the pump bell 20, Iprovide two diametrically opposed downwardly-directed locking tongues23, 23 extending substantially below the periphery of the bell, andthrough slotted openings 24, 24, formed in plates 25, 25, one mounted oneach of the rails 17 and 18. The inner face of each of the tongues 23 isnotched at 26, for a purpose to be later referred to.

In installing the pump the bell 20 is so placed that the pump barrel 22extends downwardly through the castellated nipple 8 and into the oilsupply. In this operation the tongues 23, 23 pass downwardly through theopenings 24, 24, one on each side, and the notches 26, 26, on thetongues 23, 23, are in alignment with the wedge-shaped ends 27, 27 ofthe rails 17 and 18. In this position the shaft 14 of the eccentric 13is rotated to push the rail 16 inwardly towards the pump through themedium of the link 13, and this operation serves to project thewedgeshaped ends 27 27 into the notches 26, 26, carried by the tongues23, 23, thereby firmly locking the pump in position.

The rails 17 and 18 are pivotally connected at 28, 28 to the rail 16,and a differential movement of the rails is possible because of thisconstruction. Obviously, rotation of the shaft 14 to project the rails17 and 18 towards the pump will cause said rails to slide, in theguideways 29, towards the pump but, in case one of the rails meets unduefriction, the rail 16 will pivot and continue to move towards the pumpunder continued rotation of the cam, until each of the ends 27, 27, isforced into its notch 26 in the tongues 23, 23,

and, even though one of the ends 27 were not so far advanced as itsmate, the pump would be securely retained in position.

To prevent any unauthorized unlocking of the pump, or any undesirableaccess to the aperture 5, containing the gage stick 6, I provide aprotective lid 30, for the aperture 5 containing the castellated nut 7.The lid 30 is hinged to a bracket 31, welded or riveted to the top ofthe cover 9, and extends over the shaft 14 which controls the lockingand unlocking devices for the pump, as hereinbefore set forth. The frontend of the lid 30 carries a hasp 32, which extends over a staple 33adapted to a lock 34.

As will be noted from an inspection of Fig. 2, that portion of theperiphery of the head of the cover 9 which defines the aperture 4, isflared upwardly to form a guard to prevent the passage of water and dirtunder the hood and into the oil in the drum. In. addition to thissafe-guard it may be stated that the eccentric 13 may be so forciblyoperated that the wedge-shaped ends '27, 27, will exert a very heavydownward thrust on the V tongues 23, 23, carried by the hood 20, andgreatly minimize any chance of water or dirt passing under the lower rimof the latter, since the downward thrust referred to tends to press thelower periphery of the hood tightly against the top of the cover, aswill be understood.

In the operation of the device, with the in strumentalities arranged asdescribed, and as indicated by dotted lines in Fig. 3, the pump ismerely placed in position as illustrated in Fig. 2, and rotation of theshaft 14 in the proper direction serves to project the wedge-shaped ends27 27, into the aligned notches 26, 26, in the tongues 23, 23, thewedges tightly pushing the periphery of the bell 2O downward onto thecover 9. Manifestly, rotation of the shaft 14 in an opposite directionwill release the tongues 23, 23.

From the foregoing it will be manifest that I have provided an improvedmeans for increasing the rigidity of the pump supporting member foroilvending pumps, and for detachably securing the pump firmly inposition, while at the same time providing instrumentalities preventingunauthorized operation of the pump locking mechanism, and additionalmechanism and means to prevent contamination of the oil in the drum.
